To export links from a drawing
If more than one link template exists for the set of graphical objects that you select, the Select Link Template dialog box is displayed and you are prompted to select a link template. If your selection set contains only one link template, the Export Links dialog box is displayed.
The key fields for the selected link template are included automatically. The program also exports the entity handle of the object that each link is associated with.
You may save the file in the native database format of the current table or as a comma-delimited or space-delimited text file.
